In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

The Institute of Public Administration is located in The Hague.

An international team of astronomers, including Leiden's Maciej Bilicki, has discovered an enormous supercluster of galaxies. The supercluster had previously been overlooked because it was obscured by our own Milky Way. The researchers are publishing their findings in the Monthly Notices of the Royal…

Monday June 18th the department of European Prehistory of the Faculty of Archaeology started a five-year research (2018-2022) of two newly discovered barrow groups: Baarlo-De Bong and Venlo-Zaarderheiken (northern Limburg).

Controlling fire was a turning point in the development of human civilisation. But how did fire become part of the human toolkit? The BBC radio show CrowdScience discusses the topic with Leiden archaeologists Andrew Sorensen and Kathy MacDonald.

Imagine that you need to travel, but you don’t have a car and you’re dead broke. What do you do? Hitchhiking, of course! Leiden biologists found that certain bacteria use this very same tactic: their spores hop on motile bacteria and use them as a taxi, ensuring they reach the right environment to f…

In otherwise energetic desserts at the bottom of the sea, researchers have found oases where microbes can harvest energy. Remarkably, the microbes first have to be buried under starving conditions for 80,000 years. An international group of researchers, amongst them José Mogollón from the Insitute of…

Harvesting rice from the same field, without planting new rice plants? A discovery may bring this scenario closer. Leiden scientists have discovered a gene that allows annual plants to grow after flowering, instead of dying. Publication on 13 April in Nature Plants.

Leiden University researchers have discovered by chance a note from 1783 in Papiamento. They are working on a linguistic study on confiscated Dutch letters. The ‘Letters as loot’ project is headed by Professor Marijke van der Wal.

The Leiden Academic Course Center offers a large variety of short and longer music courses. The music category includes various Singing courses, but also courses such as African percussion and Musical Workshop. A number of courses are offered at different levels.

Astronomers from the Leiden Observatory and from the University of Rochester (in the US) have discovered that the planetary ring system that covered the very young sun-like star J1407 is actually of enormous proportions. In fact, it’s much larger and heavier than the ring system surrounding Saturn.…

Over the past few years, citizen scientists from the Heritage Quest project have scoured the entire Veluwe and Utrechtse Heuvelrug areas for unknown archaeological heritage. One of the results of this research is that the number of known burial mounds in this area has doubled.
